Make quick pickled red onions in just 10 minutes with 4 simple ingredients. Tangy, crisp and perfect for burrito bowls, tacos, salads, sandwiches and more.
Using a mandolin or sharp knife, thinly slice the red onions then place in a mason glass jar or other airtight container.
Top onions with lime juice, vinegar and salt. Seal lid tightly to secure and shake well to completely submerge onion slices in brine. They're ready to enjoy after sitting for 1 hour but taste best after at least 24 hours.

Notes
Store in the refrigerator in a sealed jar for up to 2 weeks. Mandolin safety: be sure to use the hand guard as red onions can be slippery!
Vinegar Swap: I like to use red wine vinegar for a slightly deeper flavor but apple cider vinegar is milder and slightly sweeter.
Optional add-ins include thinly sliced jalapeños, whole garlic cloves or a pinch of sugar.
